CHOCK BLOCK.

Application filed May To all 'whom if; may concern:

Be it known that I, FRANK G. HEWLETT, a citizen of the United States,residing at .Bell-.tiny7 in the county of Sumter and State of Alabauia,have invented certain new and usl'ful Improvements in @hoch Blocks, ofwhich the following is a specilication.

This invention relates to a chock block, auf pertieularly to aconstruction adapted to retain in position a vehicle during transportation or when in storage.| by engagementA with a Wheel thereof.

Choc AIs of thiseharacter are very generally formed from a solid blockof Wood for the purposes of stabilit-y and economy, with -the grain ofthe ivood extending longitudi nally of the block. Such a block whenunder strain or pressure is liable to split. on the line of the grain,particularly at the upper portion which is not supported by thefastoningy devices, and it is therefore important to retain the maximumof material at this portion of the bloclr While providing at its bac aheel or flange to facilitate the introduction. of nails or securingmeans which are preferably passed through apertures previously formed inthe block. lt is also highly desirable that the face of the block at theapertures be formed to permit com` plete driving of the nails orsecuring means and prevent contact of the driving tool With the face ofthe bloclr. For this purpose it has also been found important togroove'the opposite sides of the block and thereby form flanges havingdiverging faces one of which is adapted to receive the fastening deviceswhile the other permits the direct application of a tool in the driving`of such devices.

The invention comprises a novel and improved construction of woodenblock having a wheel engaging face and an oppositely inclined outer facedisposed in a single plane and formed With a recessed portion havingWalls at a right angle to each other and jointed at their angle by acurved face provided for the introduction of a fastening device.

A further object of the invention is to provide a novel and improvedconstruction of chock block adapted to he formed from a single piece ofmaterial and provided at its 'opposite side faces With grooves formingflanges having an inclined face provided with apertures to receivefastening devices 1924. Serial No. 712,878.

for the purpose of securing the block in position.

ther and further objects and advantages of the invention Will belhereinafter set forth and the novel features thereof defined by theappended claim.

Figure 1 is a perspective of one form of the invention;

Figure 2 is a rear elevation of a modified form of the block;

Figure 3 is a side elevation of the same;

Figure t is a rear elevation of a further modification of the invention;and

Figure 5 is a side elevation thereof.

Like reference characters refer to like parts throughout the severalfigures of the drawing.

In the use of chock blocks for shipping purposes the blocks are seldomreturned to the shipper and an important element in their construction,thereforea is the economy inmaterial used and in the production of theblock for that purpose the blocks are usually formed of Wood in a singlepiece and it is desirable to form the oppositel faces thereof at suchrelative angles that a series of the blocks may he out from a singlepiece of material in the most economical manner, While in the finishingof the rblock it is essential to maintain sufficient material at theupper portion thereof to eifectually support the strain applied theretoin use. I

In the form of the invention shown in Figure `1 theblock 10 is providedwith a curved front face 11 adapted to engage. the periphery of a Wheelor vehicle tire and for that purpose may also be formed concave asindicated at 12, this face being extended from the upper to the lowersurfaces of the block so as to fit snugly beneath the Wheel. The rearface 13 of the block is inclined at an angle opposite to the front faceand preferablysuch angle is acute to the. plane of the base 14. Such aconstruction provides a body of material at the upper portion 15 of theblock sufficient to provide the proper strength of material at thisportion. For the purpose of providing a heel 16 to receive the securingmeans for the block the rear face thereof immediately above the heel isformed with a vertical Wall 17 While the face 18 of the heel is disposedat a. right angle thereto and these Walls joined by a curved portion 19at Which point the apertures 20 are provided to receive the nails orother attaching devices and extend inwardly and downwardly through theblock.

This construction provides a proper surface by which the head of thesecuring device may be driven flush with the block and space providedfor the proper manipulation of the driving tool for that purpose. Suchan arrangement avoids the difficulty of driving a headed fastener into asharp angle portion of the block as in such case the head is liable tobe driven into the wood of adjacent surfacesv and the tool brought intoviolent contact with the block, resulting in damage thereto and possiblesplitting of the. block. The opposite side walls of the block areprovided with apertures 2l eX- tending inwardly and downwardly andadapted to receive attaching devices at such points.

In the modified form of the invention shown in Figures 2 and 3, thefront and rear faces of the block are formed as before described and theopposite side faces are provided with grooves 22 having angularlydisposed diverging walls7 the. wall 23 thereof being inclined outwardly,and extending inwardly and downwardly therefrom the aperture 24 isprovided to receive the attaching device. This arrangement of saidgrooves provides an open space for the reception, of the driving tooland a plane surface to permit the complete securing movement of the nailor other device.

In the form of the invention shown in Figures 4- and 5 the outer face 25is curved or inclined and the rear face 26 formed substantiallystraight, so that with the top 27 and the base 28 a structure havingthree rectangular walls is provided. In this form of the invention theattaching heel is omitted and the base 28 may be extended to providesuliicient area for additional attaching devices. Each side of the blockis formed with grooves 29 similar to those de-y scribed in connectionwith Figures 2 and 3 and the apertures 30 for the attaching nails extendinward and downward from the lower face of the groove 29.

rIhe construction and operation of this chocl; block will be apparentfrom the foregoing description from which it will be seen that the samemay be most economically formed from the same piece of material and isadapted to retain a. suliicient body at its upper portion to resist thedownward strain thereon and prevent splitting of the block along thelongitudinal grain thereof while the disposition of the attachingapertures is so regulated as to permit the nails or other devices to becompletely set in position and suiiicient space provided for theope-ration of a driving tool and prevent its contact with the surface ofthe block. rhe provision of the said grooves affords additional securingsurface without affecting the strength of the block and permits thedirect application of the attaching devices through the flanges formedby the angle grooves which may be formed by a single operation upon aproper machine.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

A chock comprising a wooden block having a wheel engaging face andoppositcly inclined rear faces disposed in a single plane and formedwith an intermediate recessed portion having walls at a right angle toeach other and joined at their angle by a curved face provided for theintroduction of a fastening device, and grooves at the opposite sidefaces of said block forming flanges having an inclined face providedwith an aperture to receive a fastening device.

In testimony whereof I affix my signature.

FRANK e. HEWLETT.
